Abstract
Some of ground-breaking achievements of Chinese rock engineering are described in the paper. In the field of hydropower construction, the stability and monitoring technology of ship lock slope of the Three Gorges, stability and supporting technologies for high slope in deep river valley and hydropower projects and stability technology of underground large-span high side-wall caverns group were introduced. In highway and railway construction, the construction technology for passing through perennial frozen areas of Qinghai-Tibet railway, supporting technology for squeezed large deformation in Wushaoling Tunnel, construction technology of high-cold high-altitude Fenghuo Mountain tunnel and Erlang Mountain tunnel are presented, as well as geological prediction techniques for karst area tunnels. As for mining technology, a new set of coal mine roadway supporting technology system, mining technology for mixture of gas and low permeability coal seams without pillar, and safe and efficient mining technology for deep open pit were introduced. In addition, the new technology of rock anchorage and fine blasting technology were also described.
